I have a set of pioneer preimer 6.5 components in the doors as well as another 6.5 mid. I have the stock crossovers for both mids, but wont this give me a muddy sound as both mids will have the same cut off range. Should i make a custom crossover? what range? how? or buy what?
thanks

Easiest solution is to have a head unit with built in high pass x-overs for speaker outs and rcas. That way you don't have to mess around with building anything and it's tuneable on the fly to what ever sounds the best.

ok...silly question, but how do i do that when all the front speakers are coming off one amp? if i select the frequency at the deck, the amp then sees this cut off...but then i have the tweeter and mids to separate...but only one output from the deck?

oh...sorry!! I misunderstood. So both mids came with included x-overs??...They probably just divide between the mid & tweet. Are the mids all the same? Are both pairs of the mids installed in the door or is the other set in the back?

BTW most nicer Alpine decks have a switch allowing you to use the internal x-overs as a three-way set up instead of front & rear rcas....but since you only have the one amp it makes it more complicated, especially if you wish to x-over each pair of the mids at different high pass frequencies. It would be a lot simpler really (especially in the long run)to just get another amp and use the internal x-overs in the deck and run two amps for the front stage- one for the components and the other for the second set of mids...trust me you'll thank me later...plus the cost is not that different especially if you want to use nice components in your x-overs as they can add up quickly and they're not cheap...you could buy a nice amp for the same money and waaaay less effort and have way more tuneability including time correction that comes with a lot of the decks these days.

yeah...that makes sense...but right now i'm on a tight budget and just finishing up my fiberglassing work for the amps.....so buying more isnt a nice option...it does make sense though. Since i will be buying a 9833 soon anyways. I didnt relsie how exspensove crossoves can be [img]tongue.gif[/img] .
if i do go crossovers, what ranges should i go with....both speakers are at the front of the door

Are they identical speakers or is one more geared to midbass production?

Ideally you don't want the overlap from one mid to the other to be too significant as that can throw off your imaging. Midrange should only come from the set of mids which are ideally suited for imaging, probably the one furthest away from your seating position which usually is the pair furthest forward. Better to run one at like 150-200 Hz and up to your tweeter cutoff. Run the midbass one from approx 60-70 Hz to 120-150Hz if it's up to it design wise.

I just don't see it as an economical way to go as a lot of parts are required, and good ones aren't cheap. Plus you're gonna want to tinker with it...that means more parts & more $$$. I've been there and it's not worth it!

yeah..identical speakers...looks like picking up a smaller zr120 to push them will be easier

cheers for the help

or....can i run a 3 way passive crossover....maybe form another comp set...and get away with it....does having the same size mid but diff frequencies through them counter act each other?
